Question

1. read to me a lower resting heart rate often indicates a more _ heart and better cardiovascular health. worth 1.000 points. a. efficient b. balanced c. flexible 6. read to me a way to estimate your maximum heart rate is to subtract your age from _. worth 1.000 points. a. 180 b. 220 c. 240

Explanation:

Question 5

In cardiovascular health, a lower resting heart rate means the heart can pump blood effectively with fewer beats, showing efficiency. "Balanced" refers to equilibrium (not about heart rate efficiency), and "flexible" relates to adaptability (not the main aspect here). So "efficient" is correct.

The standard formula to estimate maximum heart rate is \( \text{Maximum Heart Rate} = 220 - \text{age} \). So we subtract age from 220.

Answer:

A. efficient
